Which outcome occurs more readily when forging turbine blades made from nickel superalloys at excessively high temperatures?

💡 Explanation

Increased forging temperatures promote grain boundary sliding because thermal energy weakens grain boundary cohesion, therefore the microstructure becomes more susceptible to deformation along grain boundaries, rather than allowing uniform plastic deformation throughout the grains.
